SEWlNGiVlACI-HN E ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 586,872, dated July 20,1897.

Application tiled June 17, 1896.

Be ithnown that I, WILLIAM ALBERT ScoTT, of Newcastle, in the county ofGarfield and State of Colorado, have invented new and usefulImprovements in Sewing-Machine Attachments, of which the following is afull, clear, and exact description.

This invention relates to devices designed to be attached to thepresser-t`oot of a sewingmachine for folding in the edge of the materialprior to stitching the same; and the object is to provide a singlevdevice which may be used for a number of purposes where heretofore ithas been necessary to employ a de vice for each width of hem or tuck.

My device is adapted for all widths of hemming and all sizes of tucking.

The device is also adapted for stitching` bias or straight strips ontothe surface of the material.

I will describe an attachment embodying my invention and then point outthe novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters ot' reference indicatecorresponding.;- parts in all the views.

Figure l is a plan view of an attachment embodying my invention andshowing the same as arranged for turning the edge of a material to forma narrow hem. Fig. 2 is an end elevation thereof. Fig. 3 is an endelevation showing the device as employed for turning in the edge of abias or straight strip preparatory to stitching its edge to thematerial. Fig. 4f is a perspective view of the edgeturning device. Fig.5 is a section on the line 5 5 of Fig. 4. Fig. t5 is a plan view of thedevice, showing it as adapted for wide hexns. Fig. 7 is an end elevationthereof. Fig. S is a plan view showing the device as used as a tucher,and Fig. 9 is an end view thereof.

The turning device comprises a substantially cone-shaped tube l, havingits smaller end extended toward the needle of the sewing-machine andhaving at one side a longitudinal opening' from the lower wall of whicha partition extends transversely of the tube and from one end totheother thereof. This partition is located about midway between the upperand lowersidcs of the tube, and at its forward end is provided with aSerial No. 595,853. (No model.)

downwardly-curved lip l, which is designed to turn in the edge of thegoods. There is a space between this lip 4 and the bottom wall ot thetube sui'iiciently wide for the passage of the goods operated upon.

The turning devices are attached t-o an arm 5, which at its opposite endhas rotary connection with a hand adjusting-screw 6, the saidadjusting-screw passing' transversely through a tapped hole in the shankportion of the presser-foot 7.

The device just described and particularly illustrated in Figs. l and 2is arranged for narrow tucking, but may be adjusted by means of thescrew for various widths.

In Fig. 2 l have shown a piece of cloth Sas engaged in theturningdevice, and I have shown in Fig. the edge of the strip 9 asengaged in the turning device preparatory to stitching the edge of saidstrip to a body of cloth.

In Figs. 6 and 7 I have shown a device for supporting the material whenit is desired to form a very wide hem thereon. This supporting deviceconsists of an arm lO, movable transversely of the turning device l. Ashere shown, it is movable between guide-pieces ll, secured to the underside of the turning device. The arm l0 may be friction-tight in saidguide-pieces. The end of the arm lO is provided withtransverselyextended fingers 12, and it has its end turned upward andcurved slightly rearward, as indicated at 13.

In using this device the cloth 14 is passed beneath the arm 10, carriedaround the end 13, and then its edge is inserted in the turning device,as plainly indicated in Fig. 7. It may be here stated that by making theturning device conical, as shown, theinturned portion 14 of the materialwill be decreased in width as it emerges from the smaller end of thedevice and before reaching the needle.

In Figs. S and 9 I have shown a hem-marking device in connection withthe edge-turning device. This hem-marking device cornprises an upper arml5, which extends across the upper side of the turning device, and alower arm 1G, which extends across the lower side of the turning device.The upper member`l is provided with a longitudinal slot 17, throughwhich a set-screw 1S passes to an engagement with the turning device orwith the IOO arm extended therefrom. At one side of the slot 17 theupper member 15 is provided with graduating-marks, by means of which theposition desired for the marker may be ascertained.

The free end of the lower member 16 is provided with a notched block 19,and the free end of the upper member 15 is provided with a wedge-shapedblock 20, adapted to move into the slot of the block 19 and press thegoods therein, forming a line or crease indieating the place where thehem is to be turned. Extended rearward from the free end of the uppersection 15 is an arm 21, the end of which is adapted to be engaged bythe under side of the needle-bar 22 on its downward movement, and bythis Contact the \VILLIAM ALBERT SCOTT.
